Another mid i like is dayton rs125, its labeled as 5" woofer, but membrane is small, only 4".
It goes quite low, and is good up to 5kHz. Low distortion too...

Hi Planet10!

In regards to the Peerless 5 1/4" drivers, I really like the sound, but I feel they need a bit of a low roll-off (2-3kHz) due to the response. All I can do is offer you my own measurement of the 830991 (woven fiberglass) for you to draw your own conclusions from. Would definitely have been nice to be able to cross them a little higher.

This is the 830991 in a Dayton 0.25 ft^3 / 7L cabinet. Port not spliced in, so trust nothing below 100-200 Hz.

All i can offer for the 830870 is the factory response:

We use 2 of them in a Lindgren ML-TL estimated anechoic F10 about 35 Hz. We have been using a 240 Hz 1st order PLLXO to cross them to uFonken or uMar-ken. So they should be able to meet your LF requirements.

The P might be good to about 5k, but the aluminum is difficult in reaching even 3kHz- however it's doable.

Later,
Wolf

Can you get Monacor drivers? If you can then the MSH-115 is worth a look. Very flat on axis up to 9k.

The primary reason I went with NE123 is cone material and what's behind it: smaller magnet, farther away from the cone, with sculptured, heavy duty basket to reduce rear reflections and noise. I don't know how that equates to FR and distortion, but, to me, it sounds much clearer than other 4" drivers which have a close, relatively big magnet reflecting sound directly back at the cone. Can't be good!

You could ask the same question of any two drivers. How does one justify higher cost? There was obviously some careful thought involved in the design of this driver and expense in its manufacture. It is certainly unique, not merely another scaled-down woofer.

Anyone who builds speakers should know that, unless it's grossly deformed, a FR curve has little more to do with the ultimate sound of a driver than a pretty label does to the taste of a bottle of wine.

Peace,
